Make openRecord_l more like createTrack_l for fast tracks: part 1

Use the transfer mode to distinguish use cases, as the presence of
a callback handler is not sufficient.  For example, the track could be
configured for synchronous transfer with write() or read(), and also
have a callback handler for position updates.  But that does not mean
the track can operate in fast track mode.
